Implementing Data Transition Between Hive and HBase (Python)

Function

In a Spark application, you can use Spark to call a Hive API to operate a Hive table, and write the data analysis result of the Hive table to an HBase table.

Sample Code

PySpark does not provide HBase APIs. Therefore, Python is used to invoke Java code in this sample.

The following code snippets are used as an example. For complete codes, see SparkHivetoHbasePythonExample:

# -*- coding:utf-8 -*-

from py4j.java_gateway import java_import
from pyspark.sql import SparkSession

# Create a SparkSession instance.
spark = SparkSession\
        .builder\
        .appName("SparkHivetoHbase") \
        .getOrCreate()

# Import the class to be run to sc._jvm
java_import(spark._jvm, 'com.huawei.bigdata.spark.examples.SparkHivetoHbase')

# Create class instances and invoke the method.
spark._jvm.SparkHivetoHbase().hivetohbase(spark._jsc)

# Stop SparkSession.
spark.stop()
